YOU don't need to do that by hand anymore in the 21st century ! Use Maple or Mathematica to generate reliably typeset, error-free formulae that correspond with the equations used in your projects direct from symbolic algebra worksheets. Like this:

Scientific publishers SHOULD now permit direct submission of papers prepared in Maple and Mathematica; those who don't have not understood the revolution of symbolic algebra and modern electronic publishing. And supervisors and teachers should know better than to put students through such pointless pain in the 21st Century.
